This .inventionrelates to improvementsfin building tiles and'has as one .of its objects to,,provicle a tile which may be employed in its entirety in erecting tiled building wallsand which will be so formed that it may be readily halved and the'two halves employed in erecting those portions of the build-. ing wall where half bricks or bricks disposed endwise, would ordinarily be employed.

-Another important object of the invention is to provide a tile so constructed that in erecting a building wallby the use of the tiles, the tiles maybe firmly and securely bonded to backing tiles or bricks, or' other backing material, without the necessity of employing headersor Wall ties or other connecting means.

Another object of the invention is to provide a tile embodying air spaces so arranged and formed as to provide, in the completed wall, a dead air space of maximum size without, however, weakening the tile. Likewise. the invention has as its object to provide a I tile with openings or passages therethrough at its mid-portion so arranged as to consti- 1 tute air spaces in the building wall and, at

indicated by the numeral 3 and the other by the numeral 4. The tile also is formed with a partition wall indicated by the numeral 5, which extends between the inner andouter walls 1 and 2 and in a vertical plane midway between the walls 3 and 4, thus providing air passages or spaces 6 which regis'ter in superposed tiles so as to provide dead air spaces in the walls erected by the use of the tiles. The inner wall 1 of the tile is formed in its face with vertically extending grooves indicated by the numeral 7, and the face of the end wall 4: is formed with similar grooves indicated by the numeral 8. In erecting a building wall by the use of the tiles, the tiles are arranged in tiers, the tiles in adjacent tiers being arranged in staggered relation as in the laying of ordinary brick, and-mortar is applied .to the upperwall may be backed upbybrick or other t1les,.or any other form of backing material may be employed,- andmortar-is applied to the faces of the said walls of the tiles and,

entering the grooves 7, will provide a firm and securebond between the tiles and the backing without the necessity of employing any mechanical bonds or ties. It will also sides of the tiles preparatoryto placing other i tiles thereon. By providing the grooves 7 in;

faces of the inner; walls of the tiles, the tile'eo be evident by'reference to the drawings, that whenthe tilesare laid endto end, the end i wall 8 of each tile will abut the endlwall,

4 of the tile next adjacent thereto,- in the row oftiles, and a mortar bond is, of course, I

applied between the faces of these walls and will enter the grooves 8, thus providing a firm bond between the meeting ends of relatively adjacent tiles. I I n It will be'understoodof course, that. the faces of the outer walls 20f the tiles may be finished in any desired manner.

The partition wall 5 is formed at its ends and immediately inwardly of the inner face of each wall 1 and2, with vertically extending rectangular openings or passages indicated by the numeral 9, which are preferably of the rectangular form shown in the drawings, and open through the upper and lower edges of said wall 5, and the wall is further formed, between the passages 9, with one or more vertical passages 10 likewise of recupper and lower edges of the. said wall 5.

The side of each passage 9 which is next adjacent the respectivewall 1 01 2, as the'case maybe, is defined-awall surface which occupies the same plane as the inner-face of the V respective wall '1 or 2, and this wall of each i passage 9 is'formed' with a vertically extending groove indicatedby the numeral 11, the groove of one passage 9. entering thewall 2 at a point midway between the ends of the. said wall, and the groove of the other passage 9 entering the wall 1 at a point directly opposite one of the vertical grooves 7. In mold-' ing the tile, a wire is arranged in the mold in such a manner as to form in the upper and under face of the tile, a wire groove indicated by the numeral 12, which extends fromfront to rear and medially of the opposite sides of the passages 9 and 10.

The groove 12 defines the line of cleavage on which the tile is to be broken when it is tangular form and opening through the v desired to use half tiles, and this halving of the tile may be accomplished by theuse of the ordinary trowel. One of the half tiles is I illustrated clearly in Figure 2 of the drawhalved, each half will be provided in that wall thereof which now'constitutes one end wall and which formerly constituted the partition wall 5 of the whole tile with grooves which result from thepresence of the passages 9 and 10, and which grooves now serve I or may be conveniently halved and the halves employed Where half tiles are desired or where half bricks would otherwise be employed, or whole bricks laid endwise.

It will also be evident from the foregoing,

lngs, and it will be observed by reference to 'this figure, that when one 'of the tiles is that in laying the tiles, a greater or less quantity of mortarwill enter the passages 9 and 10 and thus insure of more secure binding of superposed tiles.

'Having thus described the invention, what 'lc ai n-i A hollow building tile having a partition wall interiorly dividing the tile to provide air spaces, the said partition wall having a plurality of passages extending therethrough between itsedges whereby to weaken said wall and permit of halving of the tile, and

likewise provide mortar'grooves in the face of the intact portion of the partition wall which then constitutes one end wall of each tile half, the Walls'defining' the passages hav ing grooves in their ends, two of the first named grooves being located at the juncture of the partitionwall with the inner and outer walls of the tile body, and the walls of said passages next adjacent the innerand outer sides of the tile body having vertical grooves formed therein.

In testimony whereof I afiix my signature.
